IMPROVEMENT IN JDUMPING.,-CARS.

Specification forming part of Letters` Patent No. 199,761, dated January 29, 1878; applicationliiled l lDecember24, 1877. V

To all lwhomI it mag/concern: ,i .i V

Be it known that I, MATTHEWVAN Wonivrun,A

n of Dayton, inthe countyof0 Montgomery and State of Ohio, have inventedcertain new and `useful Improvements in Dumping-Cars,fthe.

'saine being further improvements on the one patented to me July17,1877,No.193,101; and

I do hereby declare that the following ish a full,

clear, and exactde'scriptiou of my invention, which will enableothers-skilled inthe art to which it app'ertains tomake and use the same,

l referencebeinghad to the accompanying drawings,`and to lettersof Vreference marked thereon, which form a part of this specification.

My present improvements relate toa novel construction of and combination of king-bolt lwith* its center bearing; to the construction of movable side bearings, and to the mechanism for operating the same; to the means for fast ening and unfastening the side doors, the

l same means serving to vactuate the, side bearingsg' to the mechanism for dumping; to the construction of the car-bed; and to other parts, all `as hereinafter more particularly set 'OItll; l l

In the drawings, Figure 1 represents a side elevation ofa car embodying my improvements 5 YF-ig. 2, a cross-section in the line x x Same.` C is the center-bearing circular bedplate, resting on the truck-timbers 11ha`vingl -a hole through its center `and down through the truck-timbers to allow the king-bolt to pass through, and having, also, a circular groove or ,lconoavity, d, and a rib, e, onthe upper side of "said1 plate, such rib having its top edge rounded or curved, as shown,toI adapt it to a corresponding curved groovein the head of the king-bolt,

as hereinafter described. F is a jointed rockerhinge king-bolt, its head being a circular rocker,

with"a tenon or rib, g, on. the centery of its pei riphery, to enable it more iirmly to be held in its placein the socket h, and thereby ,bring the strain upon the strongest part of the socket and rocker, and with an Iarched slot, 2, on each of its sides. I

On the A'under side of the head i of the kingjbolt isa circular groove, j, rounded or curved in its cross-section to adapt it tothe rounded edge of the rib e on the bed-plate C, and a rib,

7c, to `fit into the bed4plate when the king-bolt A &c., withoutv cutting into each other or interfer- -ing with their free action, as would be the case if tlhe top of the rib were square or the rib augu ar.

i, There isalso a socket, hf, fitting the head of this rocker king-bolt, provided with holes 1 in 4each side of said socket, corresponding in size and position to slots 2 inthe head of the kingbolt, toreceivea bolt or bolts, 3, for fastening together the rocker king-bolt and socket, forming thereby what I call the jointed rockerhinge king-bolt, and which is fastened firmly, by bolts or otherwise, securely to the under side "of theV bed-timbers and to the transom l. The

lower part of the kingbolt rocker passes through a central hole, c', in the circular bed- 'plate C, and through the truck-timbers. therethe rollers to 1it` into' the grooves q, formed by the overlapping iiangeja of a plate secured to i the lower part of vthe car-frame cverthe trucks'.

There is also a projection, s, on one end of the upper portion` of the side bearing,to,flt1a socket, t, which is fastened to the Vunder part ofthe car-bed, to hold the saidsidebearings more firmly in their places on the truck-,tim-

bers b.

The devices for simultaneously removing these side bearings from the truck-timbers b?,-

in order to allow the car to be dumped, are as` v follows, (it being understood that until these bearings be so removed they serve to bear up and support the body of the car on each side of its central supports or' bearings, and'it be-" fastened or journaled to the timbers e w, and

provided with arms zo, to which are attached bars or rods y, one to each arm, said rods being, at their outer ends, connected to the side bearings. In order to operate these 'devices and move the side-bearings away from and again back to their positions on the truck-tim# bers,.the shaft u is connected at its outer end to a lever, e, on the outside of the timberor sill 4, the shaft projecting through said sill.` It will now be seen that by moving this lever it will turn the shaft and its attached arms x, and through them the rods y y, which thus pull each its own side bearing .away from its truck on that side of the car on Vwhich it is desired'to dump, rpreparatory to such dumping. Similar mechanism is placed ony each side of the car,'eacl1 system of lever, shaft, and rods operating its own pair of side bearings. lWhen thel car has'been dumped-a reversing of the movement of lever z replaces bot-h the side bearings m in their original'positions upon the trucks. y Y

The manner of and means for fasteningvand unfastening the doors 5 ofthe car,.on which# ever side the dumping is to be made, areas follows: The same lever z which actuates the side 4bearings m also serves for this duty in regard to the doors, but at adifferent portion or stage of its movement, andv through' the in-l strumentality of a'system of slide-bar catches and levers now to be described. e A long bar, 6, of iron is pivoted or bolted toa` series of lever-catches, 7, (sayfour or more,) which serve to catch or to release the doors,as desired.

This bar y6 has a longitudinal shifting 'motion' imparted to it for operating these catches', which are centered on pivot-bolts to the outside sill of the car by means of the armor le ver @heretofore named. A lever, 8, is hung or'centered on a bolt or pivot, 9, .projectingoutward-from the car, and is provided with a slot, 10, through which said pin projects, and thisarm is connected to the'lever z.

- The operation resulting from this construction and arrangement 'of parts is as follows, viz:` When the lever z is moved, theiirst part offits Vmotion removes both the side bearings on that side of the car. After this-is effected completely the end'of the slot "10 will have been brought into contact with-the pin or-bolt 9, and it is then in position to actuate the long bar 6, and consequently the catches 7, which have not as yet been disturbed by the first portionof the movement of lever z. The fur. ther movement of said lever has no duty now to perform except to dislodge the catches and release both the doors, and consequently all the power expended on the lever at this latter stage or part of its motion is given to unfast- 'ening these doors,while all the power expended during the first part of its motion was given to moving the side bearings, so that there is no lost power, and no need of or demand for exerting at the same moment the amount of power which would be requisite to perform :both these duties at the same time, nor any need of complicating the mechanism, increasing the cost, or multiplying parts by having separate sets of devices-one set for the doors I and one for'the side bearings.

When the lever is reversed it first replaces -both-of the side bearings in their original positions upon their respective trucks, and ,after this is done the further movement of the same -lever z actuates the catches 7, and locks or carv are as follows: An iron shaft, 11, extending lengthwise of and underneath thev car` body, is secured in bearings on the car7 crossend beamsor timbers l2 and sills w w, and it is provided with a cog wheel,-A13, at one' end, which gears .into a worm, 14, on an upright shaft, 15, the upper end of -which projects above the ear-body, and is furnished with a hand-wheel, 16, and lever, or crank, for operating it. On the'long shaft llare enlargements or fixed cylinders 17, for winding and unwinding ropes or chains 18, one end yof which is fast- `ened to such enlargement and the other to one of the truck-timbers B, such ropes or chains intermediately passing down on the other sideof the shaft 11 to the center of the front truck-timber, and under a pulley, which is Afastened-to said center of the truck-timber,

4.pass from the long-shaft 11 up over the ytop ofthe Hoor-timbers and underneath the floor, to

said lastlnamed pulley 19, and then pass down andfast'en to that'end of .the truck timbersv or ironswhich is opposite the one at which the other end of this chain is fastened.

rllherefore, when the hand-wheel 16 is turned its shaft turns the long'shaft 11, unwindsfthe chain from the shaft at one of its ends, and

winds up otherportions, thereby dumping the 'car' withea'seandwithout any jar or damage.v 'A reversing"offthei'wheelv or crank lifts Vthe caribed again to l'its' original positiomfso asto be ready for loading anew. l Y Themeans for obtaining' an increased space f between? the transoms and" the truck'- timbers and truck-irons, so as toA allow space enough d for tlie carto dump or "turn over sufficiently to'discharge itslo'ad'before'coining into c011- ftactwith such timbers or" irons, as heretofore` stated, areas "follows:y Twoziron bars, 20 andl 2l, compose each transom, oneof'which,'20,

f Vpasses above thev car-timbers 'who and 22 22,'

and justfbeneatli`L the car-iioor, 'atfa point diw and 22 22, and directly beneath the bar 20, and it is curved 4or bowed'upward toward each of its ends, as shown, as it passes from underneath timbers w w up to the upper edge or portion of the inside of the sills fv fu, where each of its ends is bolted or secured to the bar 2l, thus making a strong, safe transom, and one which, at the same time, by reason of its peculiar construction and shape, and because the upwardly-bentparts oftheunderbar2lhave no bolts, beams, or other projections beneath them to occupy the clear space which they have provided; and this affords ample room for the car-bed to be dumped or tilted to discharge its load before coming in contact with the truck -timber or truck irons 5 the free space beneath the upward inclines of the barsV 2l permitting the car to be turned over to the fullest distance required before they could touch the truck-beam b, and their position preventing their touching the wheels, the latter being on opposite sides of this transom.

The bed of the car is made as follows: A broad space, 25, is left between each of the outside sills c and the sill w next adjacent thereto, these inner sills running lengthwise of the car, and the second sills, 22, are placed nearer the center of the car-bed, and also run lengthwise of the car. All the cross sills or timbers beneath these floor-sills, and which serve to support them, are so arranged that the machinery for removing the side bearings and for dumping the car will not come in contact, and will not be obstructed in its work.

It will be noticed that, instead of placing a wood transom over the trucktimbers, as usual in freightcars, I not only make a transom in the manner heretofore described, but I place the other timbers, 26, lower, and put supports 27 under them, in such position as will clear the arms :c and bars y, and also the machinery for dumping. This construction allows the car to dump or turn over sufficiently todischarge its load without coming in contaetwitli thel wheels truck-timbers, iron s, or

The center 'stakes 28, on which the doors "swing, are-braced and held to placeas follows g A short' timber, 29', beneath each` oijsaid stakes is `bolted'to the v(')utside sill,"and also to the second or-neXt adjacent sill, w,ian'd an iron bar, 30,' servvin g as abrace, passes from the center of the out- "side of' said stake obliqueljT through it, and

'down vthrough the floor and through said short "timberfand is fastened 4underneatlisaid tiniber, afnd'fwrmly holds the 'staketolplace :against all the strain it maylreceive,as"shown in Figs.

" The lever z, heretofore described, which serves to remove =theside 'bearings and open end-"namelygf "one,- 3l, ,beingan' openieiided slot,ai1'd the"otlier,`32, closed-fjatboth"fends.

adapted' to '4 enter the *dopeneiide'd slot, and' the other'one, 34, passing through the other slot,

and serving to fasten the two parts ofthe lever together. When these two parts are in line, and the pin 33 is in the open-ended slot, the whole serves as one long lever of considerable leverage and power, and is ready for use to operate the door-fastenin gs and the side bearings. A

When not needed for use the pin 33 may be disengaged from its slot or notch, and the part 32* of the lever turned down out of the way and locked to the outside of the car-frame, so that it may offer no impediment while loading the car.

In Figs. 10 and 1l I have shown another form of construction for the center support of the car upon the truck, the plate upon the truck having a ball and rocking pin projecting upward from such ball, and the under cen ter beams of the car-licor having secured to them a plate having a hemispherical socket thereon adapted to receive the ball, and a transverse slot in the bottom of such socket adapted to receive the rocking pin, and to permit the same to rock therein as the car is swayed or tilted to either side.

I claim- 1. The combination, with the bed-plate C, of the jointed rocker-hinge bolt F, adapted to project through said plate and through the truck-timbers, and provided with the groove jand rib k,'to conform to the upper face of said plate, and with the arched rib g and slot 2, adapting it for the socket h h', substantially as shown, and for the purposes described.

2. The movable side bearings m, made with flanges o and groove p, adapted to the grooved and flanged plate q r, and provided with a projection, s, substantially as and for the purpose set forth.

3. In combination with the side bearings m, the shaft u, its arms m, rods y, and lever z,

substantially as shown and described, and operatin g to move the side bearings olf the trucktimbers and to replace them again.

4. In combination with the shaft u, the lever m, slotted-lever z, link 8, barl 6, and catches,

substantiallyas shown and described, and operating to fasten and unfasten -the doors, as

set forth.y

5. The combination, with the described devices'i'or operating the side bearings m, and with the described Adevices for fastening and .unfastening the doors of one hand-lever, z, op-

erating in conjunction With the slotted link 8,

for actuating` both sets of devices consecu-v tively by one continuous movement of said 1ever, as set forth. v

- 6. In combination Withthelongitudinal shaft 11 and its gear, the-vertical shaft l5 and its gear, chain, or rope 18 and pulley 19, and the truck-timbers to which the'vchain or rope is fastened, substantially as and for the purpose vset forth.

7. The described construction of the car-bed with its longitudinal sills w, which are next adjacent to the outer sills o, placed lengthwise and near the center of the car, leaving a clear broad space between them for dumping, combined With the cross-timbers 26 and their supports or braces 27, andwhereby the dumping and the Working of the machinery may be effected without the cars coming in contact With the Wheels, or the interference of the structure with the mechanism.

8. In combination with the door stakes or posts 28, the short sills 29 and iron braces 30, passing obliquely through the posts and through the car-iioor, and secured to these sills, as shown and described.

9. In combination with the lever z, its slot 3 2 and notch 31, the extension bar or handle 32* and its pivotal pin 33 and locking-pin 34, the construction permitting this compound lever to be elongated for use, and to be shut up against the side of the car, as and for the purpose shown and described.
